Stream Video Window from Ableton Live to external device (iPad) with the least delay?

What is the most efficient way to stream the Video Window to an external device? Possible connections could be USB or LAN

No idea how to do it over USB or LAN, but you can do it via WIFI using a few different apps. I use one called splashtop.
